Objective:To observe the clinical efficacy of Bairui particles in the treatment of children with acute upper respiratory tract infection. Methods:Totally 180 children with acute upper respiratory tract infection were randomly divided into the control group and the study group. The control group was treated with conventional therapy,such as ribavirin(10 mg·kg-1 ·d-1 ,qd)and so on, and the study group received Bairui particles additionally. The improvement time of clinical symptoms,hospitalization time,clinical ef-ficiency and adverse reactions were compared. Results:Except the rale disappearance time,the improvement time of clinical symptoms and hospitalization time in the study group were shorter than those in the control group(P<0. 05). The obvious effective rate and total effective rate in the study group were also higher than those in the control group(P<0. 05). There was no significant difference in ad-verse drug reactions between the two groups(P>0. 05). Conclusion:Bairui particles are effective for the children with acute upper respiratory tract infection,which are worthy of wide clinical use.

To observe the efficacy of Bairui granules combined with ribavirin aerosol in the treatment of children with seasonal influenza. Methods:Totally 60 cases of children with seasonal influenza were randomly divided into the observation group and the control group with 30 ones in each. The children in the control group were given ribavirin aerosol, and the children in the observa-tion group were given ribavirin aerosol combined with Bairui granules. The disappearance time of symptoms and curative effect of the two groups were observed after the treatment. Results:The total effective rate of the observation group was 96. 67%,that of the control group was 86. 67%,and the difference was not statistically significant (P>0. 05). The time of fever relieving, the disappearance time of headache, whole body pain and red and swollen thoroat and cough in the observation group were all significantly shorter than those in the control group (P<0. 05 or P<0. 01). Conclusion: Bairui granules combined with ribavirin aerosol is an effective method in the treatment of children with seasonal influenza.

Objective The study was to evaluate DWI for quantifying liver fibrosis. Methods A total of 12 volunteers, 47 patients who had chronic HBV or HCV hepatitis and underwent liver biopsy [Scheuer score for fibrosis(S) and inflammation(G)] were enrolled in this study. They were scanned using a 1.5 T MR unit with b value of 0,250,500,750, 1000 s/mm~2. ADCs at b_(250-1000) and b_(500-1000) were the average ADCs of b=250, 500, 750, 1000 s/mm~2 and b=500, 750, 1000 s/mm~2. The studied the correlation between Scbeuer scores and ADC values, and conducted Mann-Whitney U test and Logistic regression to evaluate ADC for prediction of fibrosis scores. Results The average ADCs were (1.41± 0.11),(1.37±0.09), (1.27±0.05), (1.26±0.04), (1.22±0.06) mm~2/s respectively from SO to S4, stage at b=750 s/mm~2 (F=18.31, P<0.01). With the increase of fibrosis score, the average ADC decreased gradually, the two were better negatively correlated at b_(250-1000)(r=-0.727, P<0.01) than other b values. Using b_(750) and the two combined b values, the found significantly lower ADCs in S2 or greater versus S1 or less and in S3 or greater versus S2 or less fibrosis (P<0.01). The best predictor for S2 or greater was b_(750) with the largest AUC of 0.909, sensitivity of 85.7%, and specificity of 100.0% (ADC ≤1.35×10~(-3) mm~2/s). The best predictor for S3 or greater was b_(250-1000) with the largest AUC of 0.864, sensitivity of 69.6%, and specificity of 95.8% (ADC≤1.53×10~(-3) mm~2/s). Conclusion DWI can be a good predictor for scoring liver fibrosis for S2 or S3 stage above, while b_(750) and the combined b values are suitable for evaluation.

ObjectiveThe purpose of this study is to discuss the diagnostic accuracy of nornalized liver ADC using the spleen and renal cortex as reference organs for the diagnosis of liver fibrosis.Methods Forty three patients with liver disease (chronic liver disease group) at compensated stage and 10 healthy volunteers (control group) were retrospectively assessed with diffusion-weighted imaging at a 3.0 T MR unit.Liver ADC,spleen ADC,renal ADC and normalized ADC (defined as the ratio of liver ADC to spleen ADC or renal cortex ADC,S-ADC and R-ADC for short) were measured in patients stratified by fibrosis stage.Spearman analysis was used to see the correlation between fibrosis stages and ADC,one-way ANOVA was used to compare the ADCs in different fibrosis stages.Logistic regression analysis was used to determine the performance of ADC for prediction of liver fibrosis,and show the area under the curve ( AUC),sensitivity and specificity choosing the optimal cutoff value that maximized the Youden index.ResultsTen volunteers belonged to SO stage.From SO to S4 stage,there were 2,5,9,12 and 15 patients,correspondingly,liver ADCwere (1.37±0.13) ×10-3,(1.33±0.16) ×10 -3,(1.17±0.16) ×10-3,(1.23±0.14) ×10-3and ( 1.12 ±0.11 ) × 10-3mm2/s,S-ADC were 1.86 ±0.18,1.68 ±0.12,1.34 ±0.14,1.48 ±0.15 and 1.34±0.10,R-ADC were 0.71 ±0.08,0.68 ±0.12,0.61 ±0.09,0.64 ±0.11 and 0.60 ±0.08respectively,and the differences among them were significant ( F =6.48,18.70 and 3.04,P ＜0.05 ).The correlation between fibrosis stage and S-ADC was stronger than between fibrosis stage and liver ADC,R-ADC (r =- 0.71,- 0.51,- 0.41 ;P ＜ 0.01 ).S-ADC was superior to liver ADC and R-ADC for detection of S2,S3 and S4 fibrosis stage (Youden index:0.91,0.58,and 0.59).ConclusionSpleen normalized liver ADC improves diagnostic accuracy for detection of liver fibrosis than liver ADC and renal normalized liver ADC.

Objective To evaluate the quality of life for tuberculosis patients after anterior debridement, autograft bone fusion and anterolateral fixation operation. Methods 17 cases of thoracolumbar spinal tuberculosis were treated surgically from January 2008 to March 2011. All the cases underwent anterior debridement, autograft bone fusion and anterolateral fixation operation. MOS health survey 36-item Short Form (SF-36), Japanese Orthopaedic Association Scores (JOA) and Visual Analogue Scale (VAS) were used to evaluate the quality of life, spine function and pain symptom before and 1 and 6 months after surgery. Results Compared to the results 1 month after surgery, the scores of physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social function (SF), role emotional (RE), and mental health (MH), and JOA subjective symptoms, JOA clinical signs, and JOA daily activity limitation, and VAS improved (P<0.05) 6 months after surgery; compared to pretreatment, the scores of PF, BP, GH, VT, SF, and MH, and JOA subjective symptoms, JOA clinical signs, and JOA daily activity limitation, and VAS improved (P<0.05). Conclusion The anterior debridement, autograft bone fusion and anterior fixation operation is effective to improve the quality of life, spine function and pain symptom for tuberculosis patients.
